There are couple of options you can provide on the terminal to fuser. The main purpose of the binary is to check the process id of the process using the file. This can be useful if some file operation on a file is blocking something for you 🙂

I was trying to get templates to work on evolution and found that although templates are there in evolution mail client, its not that efficient to use. What I thus wanted was to have something that could allow me to send mails to (and cc and bcc) to specified people with predefined template, only some values changed, like changelog and so on. So I wrote a set of files and below files to achieve the same. Hope it helps you too 🙂

First we will have a file called \”fields\” containing all the variable that we intend to use:

Ok, so here we are defning the to field, cc field and the other fields along with the name of the file to attach. Next we need the template to use. Create a file called \”template.changelog\” as defined in the above file:

On my personal desktop at home, I like to see the statistics at least once a day, for what was installed, what was run with sudo and other such details like kernel errors.

Running this monotonously every day is quite boring, so comes to rescue is logwatch. I have Fedorainstallation so I will talk about the location with respect to that so for your distribution it might be a little different.

First install logwatch using 🙂 yum install logwatch

and you are done.

If you need to do more configuration and want to see something different in the mail that is sent( BTW sendmail is assumed to be default mail client), the keep reading.
First open the file /etc/logwatch/conf/logwatch.conf
The contents for my distro is just one line 🙂
# Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf)
So, open the file /usr/share/logwatch/default.conf/logwatch.confbr
I will highlight the important lines in the file here:LogDir = /var/log — This is the directory for all the log filesMailTo = root — Whom should the mail be sent toPrint = If this is set to true then there will be no mail sent and the output will be displayed on the stdout.Detail = The level of details you want to see in the mail or the output on screen.

Thats pretty much it.. If you want to further modify the details in the mail you can configure the services. For more advanced usage you can even go to/usr/share/logwatch/scripts/services and configure the individual scripts.
